NOTE: I am not putting a ConfigurationGroupName in there because on all previous attempts, when I had passed it in, the program did nothing. Having removed the ConfigGroupName, it actually does a lot. Goes along for quite some time, presumably evaluating policies.
Ultimately, there is no policy data created. I just have a huge page of what appears to be the same error again and again:

Invoke-PolicyEvaluation : Property 'IsHadrEnabled' does not exist.
At D:\directoryname\EPM_EnterpriseEvaluation_3.0.0.ps1:81 char:27

Since SQL Server 2012 has System Policies for viewing the health of Availability Groups, the PowerShell script will run Invoke-PolicyEvaluation for each Policy in the store.
A System Condition used in the AlwaysOn System Policies checks the Server Property "IsHadrEnabled" , but that property doesn't exist for versions lower than SQL Server 2012.

I modified the PowerShell script to skip all policies with a name starting with "AlwaysOn" and the script ran without errors.
